Definitions
- the invention relates to an internal combustion engine with exhaust gas turbochargers according to the preamble of claim 1.
- Exhaust gas turbochargers are known to be used in internal combustion engines to increase performance.
- DE 195 24 566 Cl shows an internal combustion engine with exhaust gas turbochargers which are arranged in a carrier housing. The turbines are located inside the carrier housing and the compressors are located outside the carrier housing. The turbines are supplied with exhaust gas in parallel via a common exhaust gas supply. After the exhaust gas has flowed through the turbines, it is collected in a collecting pipe - a downpipe is shown. The arrangement is chosen so that the exhaust gas from opposing turbines is brought together. This results in a large overall length of the header pipe.
- the external dimensions of the carrier housing result from the number of exhaust gas turbochargers used, their size and the exhaust gas supply or the manifold.
- the carrier housing with the inlets and outlets is attached to the top of the internal combustion engine.
- This increases the installation space requirement of the internal combustion engine.
- an increase in the space requirement is problematic.
- the invention is based on the object of designing an internal combustion engine with first and second exhaust gas turbochargers, which are arranged in a carrier housing, with compact external dimensions.
- the invention provides that the two exhaust gas turbochargers are arranged in such a way that the two supercharger axes are at an angle between 55 to 100 degrees to one another and lie in the same plane.
- the plane extends parallel to the top of the internal combustion engine.
- the arrangement brings about a low swirling merging of the exhaust gas volumes of the two exhaust gas lines after the two exhaust gas turbochargers. Another advantage is a shorter manifold compared to the prior art.
- the air supply of uncompressed air to the two exhaust gas turbochargers is arranged on the outside above the cylinder heads.
- a filter can be installed upstream of the air supply in the direction of the opposite side of the force.
- the arrangement of the air inlets reduces the installation space requirement, i. H. the internal combustion engine with the exhaust gas turbochargers has more compact external dimensions.
- a third exhaust gas turbocharger is arranged within the carrier housing, the supercharger axis of which likewise lies in the same plane and within the above-mentioned angular range.
- the exhaust gas from this centrally located exhaust gas turbocharger is fed into the common manifold.
- the exhaust lines for the first and second exhaust gas turbochargers are preferably with an exhaust flap for register switching Mistake.
- the air supply to the third exhaust gas turbocharger takes place via a branch from the air supply lines to the first or second exhaust gas turbocharger. By arranging the branch downstream of the filter, the third exhaust gas turbocharger does not need its own filter. This also reduces the installation space.
- the charge air compressed by the exhaust gas turbochargers is combined in a charge air guide, which is arranged in the center of the cylinder V.
- Figure 1 shows an internal combustion engine with a first and second exhaust gas turbocharger
- Figure 2 shows an internal combustion engine with three exhaust gas turbochargers.
- Figure 1 shows an internal combustion engine 1 with a first exhaust gas turbocharger 2 and a second exhaust gas turbocharger 8 with a view of the top.
- the functionality of exhaust gas turbochargers is assumed to be known in the following.
- the first exhaust gas turbocharger 2 comprises a compressor wheel 3 and a turbine wheel 4 coupled by means of a shaft.
- the axis of rotation of the compressor wheel 3 and turbine wheel 4 is designated in FIG. 1 as the supercharger axis AI.
- Uncompressed air Lzu is conveyed from the compressor wheel 3 into a charge air guide 11 via an air supply 6 with an upstream filter 5. The direction of flow is indicated by arrows.
- the air supply 6 of uncompressed air to the first exhaust gas bolader 2 is arranged above the cylinder heads 14.
- Exhaust gas is supplied to the turbine wheel 4 of the first exhaust gas turbocharger 2 via an exhaust gas supply 7. After it has flowed through the turbine wheel 4 centripedally, it is guided into a collecting tube 13.
- the second exhaust gas turbocharger 8 comprises a compressor wheel 9 and a turbine wheel 10.
- the axis of rotation of the second exhaust gas turbocharger 8 is designated as the supercharger axis A2 in FIG.
- Uncompressed air Lzu is supplied to the compressor wheel 9 via an air supply 16 with an upstream filter 15.
- the air supply 16 of uncompressed air to the second exhaust gas turbocharger 8 is arranged above the cylinder heads 14.
- the compressor wheel 9 conveys the air into the charge air guide 11.
- the turbine 10 becomes the exhaust gas via an exhaust gas supply 17
- the two exhaust gas turbochargers 2 and 8 are arranged in a carrier housing 12. Here, their turbines 4 and 10 are arranged inside the carrier housing 12 and the compressor wheels 3 and 9 are arranged outside the carrier housing 12.
- the collecting tube 13 is likewise arranged within the carrier housing 12.
- One of the two exhaust gas turbochargers can be provided with an exhaust flap for charging the register.
- a central exhaust gas outlet 22 connects to the header pipe 13, as seen in the plane of the drawing, to the left.
- the first 2 and second exhaust gas turbocharger 10 are arranged in the carrier housing 12 in such a way that the two supercharger axes AI and A2 are at an angle between 55 to 100 degrees to one another and lie in the same plane E. The angle is designated by Phi in FIG. 1.
- the arrangement results in a turbulence-free e Merging the two exhaust gas flows with a short overall length of the header pipe 13.
- FIG. 2 shows an internal combustion engine 1 in which a third exhaust gas turbocharger 18 is additionally arranged within the carrier housing 12.
- the supercharger axis of the third exhaust gas turbocharger 18 lies in the same plane E as the supercharger axes AI and A2 of the first 2 and second exhaust gas turbocharger 8.
- the supercharger axis of the third exhaust gas turbocharger 18 divides the angle Phi into two equal angular ranges, for example 50 degrees.
- the compressor wheel 19 of the third exhaust gas turbocharger 8 is supplied with compressed air via a branch 21 from the air supply 6 and the air supply 16.
- the third exhaust gas turbocharger 18 is additionally arranged within the carrier housing 12.
- the supercharger axis of the third exhaust gas turbocharger 18 lies in the same plane E as the supercharger axes AI and A2 of the first 2 and second exhaust gas turbocharger 8.
- the supercharger axis of the third exhaust gas turbocharger 18 divides the angle Phi into two equal angular ranges, for example 50 degrees
- Exhaust gas turbocharger 18 turbine wheel 20 exhaust gas flowing through is introduced into the manifold 13.
- the charge air conveyed by the compressor wheel 19 is fed to the common charge air guide 11. This is arranged in the center of the cylinder V.
- the arrangement of the exhaust gas turbocharger results in a smaller carrier housing compared to the prior art;
- the arrangement of the air feeds of non-compressed air above the cylinder heads results in a higher packing density and a smaller external dimension of the internal combustion engine;
- Internal combustion engines within the same series can have a 2-charger or 3-charger arrangement with less difference in parts.
